2006 Sierra F28.
Very slight delam about 4 inches wide and about 3 feet long vertically right under the gutter drain. Left front. I am guessing it is from a roof leak that froze. No roof leaks now.
I bought it that way. Got a pretty good deal on the trailer and in the past two winters it has not grown at all. If it ever decided to grow I can fix it properly. If not I will trade it back in to the dealer I bought it from without issue. I have done business with them for years.
